Question

Which postualte or theorem could be used to prove that EFG = HFG?

Answer 1

Answer:

AAA (Angle-Angle-Angle) Theorem

Step-by-step explanation:

We see that $\angle E\cong\angle H$, $\angle F$ is congruent to itself, and $\angle G$ is congruent to itself. Thus, with 3 angle congruency statements, we could use the AAA Theorem to prove that the triangles are congruent to each other.
